At leat the astonauts will be able to phone home when they get to the moon, though putting a phone box on the lunar surface is totally unnecessary with everyone having a mobile. Then again mobiles are quite small and perhaps they couldn't type in the number using space gloves.

seriuously, the problem is not so little, also assuming it's internal space will be enough to host four astronauts (like fishes in a barrel...) this very expensive vehicle will have NO life support redundancy NOR margins for extended missions' duration, that's VERY BAD for a "plan" that's going to cost over $230 billion in the next 20 years!!!

also, a so small (just to fit four astronauts) Altair, clearly shows what I've ALWAYS said in latest two years on my website and blog and on space forums: the current Ares-5 is underpowered and its "130 mT payload" target is too little (that's why I've suggested to develop a 200+ mT cargo launcher)

...the original LM had no redundancy, no margins and very little space...

an excess of risks was very common (and inevitable) in the early years of spaceflights (that's why the Shuttle was designed without escape systems) but, today (especially after the Challenger and Columbia accidents) this kind of (evitable) risks are unacceptable since, now, the technology allows to reduce it to a minimum

Being able to live in a barrel is part of being an astronaut.

unfortunately, the Altair crew cabin seems very much smaller than a fishes' barrel...

If they had bigger launcher the responsible thing to do would be more people in a slightly larger barrel, not luxury apartments for everybody.

send twenty astronauts for a week is irresponsible and irrational, while, send four astronauts for a month is rational and economical

...those phone booths are not the correct scale when compared to an astronaut...

The phone-booth near the Altair ascent-stage looks too big, since, the astronaut near it is not in his full size, but a little back and down in the image (probably on a platform or a stairs) so, his image doesn't starts from the "lunar boot", but just near his knees, up.
